STATUS_STRICT_CFG_VIOLATION

Strict Control Flow Guard rejected the image

Windows returns STATUS_STRICT_CFG_VIOLATION when process security or execution policy rejects the requested state or operation. A process requiring strict CFG attempted to load an image that does not provide the required Guard metadata. A valid signature alone does not satisfy this mitigation.

Inspect PE load-config Guard flags and toolchain settings for every loaded module, including plugins and injected DLLs. Rebuild or replace the incompatible image.

The important artifact is the image that failed the strict CFG requirement. Identify that module and its build flags first; disabling strict CFG globally would hide a compatibility or toolchain defect instead of correcting it.
